From ecbf02791f921b39594719ea103ae66ed2fce095 Mon Sep 17 00:00:00 2001 From: Brooks Davis Date: Fri, 28 Oct 2022 00:55:45 +0100 Subject: [PATCH] freebsd: simplify MD isa_defs.h Most of this file was a pile of defines, apparently from Solaris that controlled nothing in the source tree. A few things controlled the definition of unused types or macros which I have removed. Considerable further cleanup is possible including removal of architectures FreeBSD never supported. This file should likely converge with the Linux version to the extent possible.
